Everything will need changed, but it’s up to you when you change them. The lifetime covers the lifetime of the implant against rupture, not your lifetime (lots of PC’s have made it sound like its your lifetime) which is around 10-15 years, each case is different.
I have had CUi’s and responsives (lifetime implants) and to be honest, they are both great implants, they go through over 100 different tests each implant and take almost two weeks to make one. A lot of surgeons prefer the CUi’s as they have been around longer. It’s your personal choice though Hun xx
